Happy St Patrick's Day

Take your pick:

Kaitlin was a winsome young lass,
Who was cursed with odiferous gas,
Sean said "Don't y'know",
"That the cabbage must go"
"Ere I make ye an amourous pass"

Kaitlin was a winsome young lass,
Who was cursed with odiferous gas,
But it wasn't the stink,
That drove men to drink,
But the shape of the young lady's ass.
